Answer:
y=3x+9
Step-by-step explanation:
Slope intercept form: y=mx + b
m= slope
b= y-intercept
-Plugin the point
-3=3(-4)+b
-3(+12) = -12 + b(+ 12)
9=b
y = 3x + 9
Taylor miah Ashlee go out to eat at a restaurant they each order the same meal Taylor has a coupon for 2.25 off her meal miah has a coupon for 1.50 off her meal if the total for all three meals is $27 after applying both coupons how much does Ashlee meal cost before tax
Answer:
$23.25
Step-by-step explanation:
If you add both coupons (3.75) from the total of the meal without the tax you get 27 - 3.75 = 23.25 dollars

For 1992 through 1994, the per capita consumption of fish and shellfish in the
u. s. increased at a rate that was approximately linear. in 1992, the per capita
consumption was 14.7 pounds, and in 1994 it was 15.1 pounds."
36. write a linear model for the per capita consumption of fish and shellfish
in the u. s. let t represent the number of years since 1992.
37. what would you expect the per capita consumption of fish and shellfish
to be in 2002?
Answer:
The answer is below
Step-by-step explanation:
A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.
Let t represent the number of years since 1992, and P represent the per capita consumption of fish and shellfish in the U.S.
In 1992 (t = 0), the per capita consumption was 14.7 pounds, this can be represented by (0, 14.7) while in 1994 (t = 1994-1992=2) it was 15.1 pounds this can be represented by (2, 15.1)
Using (0, 14.7) and (2, 15.1) we can get the equation of the line using:
[tex]P-P_1=\frac{P_2-P_1}{t_2-t_1}(t-t_1)\\ \\P-14.7=\frac{15.1-14-7}{2-0}(t-0)\\ \\P-14.7=0.2t\\\\P=0.2t+14.7[/tex]
In the year 2002 (t = 2002-1992 = 10), the per capita consumption of fish and shellfish is:
P = 0.2(10) + 14.7
P = 16.7 pounds

convert .932 into a fraction
Answer:
932/1000
Step-by-step explanation:
To write .932 as a fraction you have to write .932 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.932 = .932/1 = 9.32/10 = 93.2/100 = 932/1000
And finally we have:
.932 as a fraction equals 932/1000
Answer:
923/1000

Answer:
A & B
Step-by-step explanation:
See attachment for complete question
Given
[tex]y = \frac{1}{2}x[/tex]
Analyzing the given options
Option A:
[tex]6y = 3x[/tex]
Divide both sides by 6
[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]
[tex]y = \frac{3x}{6}[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is true for the given expression:
Option B:
From the graph:
x = 2, when y = 1
x = 4, when y = 2
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 -1}{4 - 2}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{2}(x - 2)[/tex]
[tex]y - 1 = \frac{1}{2}x - 1[/tex]
Add 1 to both sides
[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is also true for the given expression.
Option C:
From the graph:
x = 2, when y = 4
x = 4, when y = 8
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 4}{4 - 2}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = 2(x - 2)[/tex]
[tex]y - 4 = 2x - 4[/tex]
Add 4 to both sides
[tex]y - 4 + 4= 2x - 4 + 4[/tex]
[tex]y = 2x[/tex]
This isn't true for the given expression.
Option (D):
From the table:
x = 2, when y = 1
x = 4 when y = 3
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3 - 1}{4 - 2}[/tex]
[tex]m = \frac{2}{2}[/tex]
[tex]m = 1[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = 1 * (x - 2)[/tex]
[tex]y - 1 = x - 2[/tex]
[tex]y = x - 2 +1[/tex]
[tex]y = x - 1[/tex]
This isn't true for the given expression.

A rectangles width is 13 more than its length. If the perimeter is 82 feet what is the length and width.
Answer:
Step-by-step explanation:
Lenght should be the greater here. I am considering your question however.
Let length side is 'x'.
The width side is 'x +13'
Perimeter of a rectangle : 2 ×( length + width)
given that perimeter is 82
2 × ( x + x + 13) = 82
2 × ( 2x + 13) =82
4x + 26 = 82
2x = 56
x = 28 cm
length is 28
width is 41

Answer:
I had no idea what u were asking but i solved for r and got r>45
Answer:
r > 45
Step-by-step explanation:
6 <-3 + r/5
add 3 left and right of the < sign gives:
6 +3 <-3 +3 + r/5
9 < 0 + r/5
9 < r/5
multiply left and right of the < sign gives by 5 gives:
9 * 5 < 5* r/5
45 < r
r > 45
Complete the process of solving the equation. Fill in all missing terms and select all missing descriptions. Simplify any fractions. 11a+2=9a+4 2a+2=4 Add 9a to both sides Subtract 9a from both sides Multiply both sides by 9a Divide both sides by 9a Apply the distributive property 2a= Subtract 2 from both sides a= Divide both sides by 2
Answer:
11a + 2 = 9a + 4 ( Subtract 9a from both sides)
11a - 9a + 2 = 9a - 9a + 4
2a + 2 = 4 (Subtract 2 from both sides)
2a + 2 - 2 = 4 - 2
2a = 2 (Divide both sides by 2)
2a/2 = 2/2
a = 1
Step-by-step explanation:
Simplify any fractions.
11a + 2 = 9a + 4
2a + 2= 4
We simplify as shown below
11a + 2 = 9a + 4 ( Subtract 9a from both sides)
11a - 9a + 2 = 9a - 9a + 4
2a + 2 = 4 (Subtract 2 from both sides)
2a + 2 - 2 = 4 - 2
2a = 2 (Divide both sides by 2)
2a/2 = 2/2
a = 1

Felipe and Makayla each tried to solve the same
equation for x.
Original equation: 2x + 6 = 3x - 8
The result of Felipe's first step was -x + 6 = 8.
Describe the first step Felipe made to the equation
Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8
What is a function?
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is the equation equating two functions as -
2x + 6 = 3x - 8
We have -
2x + 6 = 3x - 8
2x - 3x + 6 = 8
-x + 6 = 8
Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8

Step-by-step explanation:
Gabriela Mistral was a poet, diplomat, teacher and humanitarian. Each week she worked a certain amount of days as a poet diplomat teacher and humanitarian. This ratio was one day as a poet to one day as a diplomat to three days as a teacher to two days as a humanitarian how many days must she work as a humanitarian if she works 12 days as a teacher?
Answer:
Gabriela Mistral works as a humanitarian for [tex]8[/tex] days.
Step-by-step explanation:
Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.
Ratio is [tex]1:1:3:2[/tex]
Let [tex]x[/tex] denotes total number of days Gabriela Mistral work.
As she works 12 days as a teacher,
[tex]\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28[/tex]
Total number of days [tex]=x=28[/tex]
So,
she works as a humanitarian for [tex]\frac{2}{7}x=\frac{2}{7}(28)=8[/tex] days.
